Eye glazed over

Today I noticed the right eye on my octopus is glazed over a little bit. I attached pictures of each side so you can see the difference. He also seems to be pulling his right eye more in to his body than his left, which you can see on the picture of all of him. Let me know if I should be worried or if it will go away. He's shedding suckers like crazy too. I know that's normal but maybe could help to know what is going on.

Sounds like some kind of bacterial infection. How is the water quality? The eye does not sound very serious at this point. I would recommend water changes over the next couple of days regardless of your actual water quality values.

That's correct. I got him Friday morning. Tested water Wednesday and it was:

Amm-0
Nitrite-.1
Nitrate-5
pH-8.1
phos-0

Did a 5 gallon water change Thursday even though water tested fine. Should I do 2 5-gallon water changes over the next couple days? Tank is 55 gallons. Has eaten a frozen shrimp, and today killed and ate an emerald crab and an astrea snail.

I think that might be what will happen with his eye. He doesn't show it very often. Always watches me with his good eye while he cruises around on the glass. Where do I get tetracycline and is it expensive?

Carol- He is most likely O. Filosus. If you search google type "Caribbean two-spot octopus", you will find a lot more results. Does Biddle have eyespots? If not he isn't the same species. The eyespots on mine aren't very noticeable unless you know they are there and are looking for them. When he hunts/gets scared he will flash them bright blue but otherwise they are usually hidden under his mantle.

mosthated- I got him from saltwaterfish.com on Tuesday. A lot of other members have gotten their octos from there as well. Animal mother got his approximately a week before I got mine.

I will take more pics tonight. It seems to have progressed quite a bit, but he doesn't seem bothered by it.

Sorry it took so long here's more pics. It is definitely farther along than the other pictures. The first picture is to compare the 2 eyes. You can tell his right eye (left side of pic) is pulled in. Next is his normal left eye. Then his right.

Tetracycline should help to combat the bacterial infections associated with the eye problem. I presume it is still getting worse? In my experience I have found that eye problems are merely a symptom of a systemic bacterial infection, thus untreatable. If the eye problem is mechanical, the tetracycline should help.

Almost 4 months. Yeah my levels were perfect when I tested last week. Did a water change a day after that anyway, and one Sunday (I think). Only thing is CA and Alk could be a little out of wack. They were in my nano reef, and they are almost down where they should be after 20% water changes every day.

You might want to get other opinions on the Melafix before adding it, it is bad for seahorses but I don't know about Octopuses.

Also, you may want to try to gut load some of his food with the tetracycline. Most antibiotics work better from the inside. I injected Trapper's shrimp when she was brooding as a precaution against skin infections. How much good it did I cannot say (she lived an excessive amount of time after the hatching but what to attribute it to is an unknown) but I know it did not harm.
